General description

Sampling and subsequent analytical determination of airborne N,N-dimethylcyclohexylamine has been reported.

Application

N,N-Dimethylcyclohexylamine has been used:
  • as switchable hydrophilicity solvent (SHS) for the extraction of lipids from freeze-dried samples of Botryococcus braunii microalgae for biofuel production
  • as catalyst in three-component organocatalyzed Strecker reaction on water

In the present work, the effectiveness of switchable hydrophobicity solvents (SHSs) as extraction solvent (N,N-Dimethylcyclohexylamine (DMCA), N,N-Diethylethanamine (TEA), and N,N-Benzyldimethylamine (DMBA)) for a variety of emerging pollutants was evaluated. Different pharmaceutical products (nonsteroidal anti-inflammatory drugs (NSAIDs), hormones, and triclosan) were
